LFM3 is Liquid AI’s family of open-weight foundation models, built around a shared LFM3-1.7B-Base backbone. The family includes text, vision-language, audio, omni, and decision models, with variants specialized for different inputs and outputs. Liquid AI describes the models as designed for local deployment and fine-tuning, including on a single GPU; the text model has a documented 256K-token context window. The models are available through model repositories, Liquid AI’s API, and its Playground. Documented uses include tool calling, speech interaction, video understanding, and structured decisions.
